COLLEGE PARK, Maryland (Ticker) -- Duke's heralded freshmen were introduced to a new side of college basketball - their first loss.
Drew Nicholas scored 24 points and Jamar Smith sparked a key run as No. 15 Maryland ended the top-ranked Blue Devils' 12-game winning streak with an 87-72 Atlantic Coast Conference victory.
Duke (12-1, 2-1 ACC) entered as the nation's lone unbeaten team after winning 12 games to start the season for the second straight year. The 13th game again tripped up the Blue Devils, who suffered a memorable 77-76 loss to Florida State in their 13th contest last season.
Maryland (10-4, 3-1) knocked off a top-rated Duke team at home for the second straight season. Last year's 87-73 triumph was at Cole Field House and this was the first visit by a No. 1 team to the new Comcast Center.
"It's the first time we've had a No. 1 team at Comcast Center," Nicholas said. "It's the first time we've played this hard for 40 minutes."
A basket by Smith with just over 14 minutes left gave Maryland the lead for good, 55-53. It started a decisive 18-4 run that opened a 14-point cushion.
Smith scored all of his eight points in the run, during which Maryland held Duke to one basket over five-plus minutes. Freshman Chris McCray's jumper capped the burst to make it 71-57 with 9:20 to go and McCray waved his arms in celebration, much to the delight of the sellout crowd.
Freshman J.J. Redick, the crown jewel of Duke's star-studded recruiting class, fouled out with 13 points after a 34-point performance against Virginia on Wednesday. The Blue Devils made 37-of-40 foul shots in that game but were just 9-of-20 in this one.
"We're concerned about everything," Duke coach Mike Krzyzewski said. "We've got a team that still has a lot of development, and this is not a good effort on our part."
Redick's classmates also struggled as Shavlik Randolph managed five points on 2-of-8 shooting and Shelden Williams had three. Duke's six freshmen combined for 25 points.
Ryan Randle collected 15 points and 17 rebounds as he exposed the Blue Devils' weak inside game. Beefy Tahj Holden added 10 points for Maryland, which converted 21-of-22 foul shots in the second half.
The Terrapins shot a sizzling 93.5 percent (29-of-31) at the line, becoming the first team to attempt more free throws than the Blue Devils this season. It came after Wednesday's loss at Wake Forest in which Maryland coach Gary Williams was upset after the Demon Deacons shot 42 foul shots.
"It's hard to put a game situation into a free-throw practice," Gary Williams said. "You can't imitate the pressure. We just shoot them, and we were on our game today. It's amazing, when you play good defense and run your offense how you shoot good free throws, too. It just seems like that's part of the package."
Randle's big effort keyed a 43-32 edge on the glass for Maryland as Blake added seven rebounds. Duke's starters combined for just eight boards.
"Maryland played like a veteran team and we played like a young team," Krzyzewski said. "Drew Nicholas was sensational and Randle, I think, had more rebounds than all of our big guys together. He got every rebound, he played a great game."
Duke jumped out to a 13-3 lead and had the better of the play in the first half. Redick nailed a 3-pointer just before the halftime buzzer for a 43-37 advantage.
Maryland opened the second half with nine straight points, grabbing a 46-43 lead on a 3-pointer by Steve Blake with 18:35 remaining. Blake led all players with six assists.
"We just tried to keep the focus at the half, that we were playing good defense," said Gary Williams, who notched his fifth victory over a No. 1 team. "I thought in the second half our execution on the offensive end was as good as it's been any year against a quality team."
Blake also helped hound Duke point guard Chris Duhon into 3-of-10 shooting. Duhon, the nation's assists leader, handed out only three.
But backup point guard John Gilchrist, a freshman, helped spark Maryland's decisive tear. The heir apparent to Blake, Gilchrist finished with six points and three assists in just 10 minutes.
"John is our future point guard, he is going to to be really good," Williams said. "He thinks he's really good now and I'm not going to tell him any different."
The Terrapins have won 13 straight ACC home games since a 74-71 loss to Florida State on February 14, 2001. Maryland improved to 1-4 against ranked opponents this season.
Six of the last seven meetings have been won by the team that trailed at halftime.
